PAULA ,SIMON AND RANDY COLLECTED INSECTS FOR THEIR SCIENCE PROJECT. AT THE END OF THE FIRST WEEK PAULA AND RANDY TOGETHER HAD 89 INSECTS, RANDY AND SIMON TOGETHER HAD 85 INSECTS. HOW MANY DID EACH HAVE ALONE?

  • Math -

    P + R = 89
    R + S = 85
    You need a third equation to solve for all three unknowns. Is that the only information you were given?

  • Math -

    RANDY AND SIMON TOGETHER HAD 80

  • Math -

    That disagrees with you previous statement "RANDY AND SIMON TOGETHER HAD 85"

    When you finally get three independent statements stated as equations, then use algebra to solve them.
